Again, the 2nd communicator judges whether the communication object information of the 2nd communicator self changes, and can only under situation about changing communication object information be sent to server unit.Under these circumstances, the 2nd communicator 402 has formation described below.
Also can have the information that detects the usefulness of communicating by letter with the 2nd communicator 402, be the change-detection communication object change in information, not shown portion.When communication object information sending part 40203 detects the communication object change in information in change-detection portion, communication object information is sent to server unit 403.
In the flow chart of Fig. 5,, also can regularly obtain communication object information though do not address the situation that obtains communication object information.In addition, also can be only when the 2nd communicator mobile causes that communication object information changes, by sending communication object information to the 2 communicators from the base station etc., obtain communication object information.
Again, usually communication object information sending part 40203 also sends to server unit 403 with communication object information together with the intrinsic information of the 2nd communicator 402.Server unit 403 is rewritten corresponding to this intrinsic information that is paired communication object information.
The flow chart that utilizes Fig. 6 below to server unit 403 receive, the action of poll object information describes.
(step S601) communication object message pick-up portion 40301 judges whether to have received communication object information.If received communication object information, just enter step S602, if received communication object information is not then returned step S601.
The registration place of the communication object information that receives among (step S602) communication object information update section 40302 searching step S601.The place of registration is in communication information storage part 10301.Here, the retrieval in the place of so-called registration, what say is such as following such processing.
Communication object message pick-up portion 40301 receives for example intrinsic information of communication object information and the 2nd communicator 402 in pairs.Again, communication object information update section 40302 is made key with the intrinsic information that receives, and obtains the communication information with communication object information.
(step S603) communication object information update section 40302 retrieves the communication object information registering that receives among the step S601 in step S602 registration place.
Below the concrete action of the communication system of present embodiment is described.
Here, the 1st communicator, the 2nd communicator are the mobile portable phones.
Server unit stores the communication information shown in Figure 3.In addition, the intrinsic information of supposing the 2nd communicator is " 010-2222-3333 ".That is the 2nd communicator be the IP phone of utilizing the Internet.
Here, the 2nd communicator moves, and follows it to move, and the communication object information of the 2nd communicator changes.The communication object information of the 2nd communicator of supposing to follow moving of the 2nd communicator and changing is " 1080::5:2A11:11DE:555C ".
The 2nd communicator receives the IP address " 1080::5:2A11:11DE:555C " of distributing to the 2nd communicator from the radio communication base station of for example mobile object.And the 2nd communicator the IP address " 1080::5:2A11:11DE:555C " that receives is sent to server unit.During transmission, the 2nd communicator also sends to server unit to the intrinsic information of self " 010-2222-3333 ".
Server unit receives IP address " 1080::5:2A11:11DE:555C " and intrinsic information " 010-2222-3333 " from the 2nd communicator.Then, server unit will be " 1080::5:2A11:11DE:555C " corresponding to the communication object information-change of the intrinsic information " 010-2222-3333 " in the form (communication management information table) of Fig. 3 supervisory communications information.Therefore, the communication management information table becomes as shown in Figure 7.
In addition, when the 2nd communicator detects the communication object change in information in change-detection portion, also communication object information can be sent to server unit.In addition, also the 2nd communicator when obtaining communication object information, always communication object information is sent to server unit.
In addition, server unit also can be registered the communication object information that receives from the 2nd communicator usually.In addition, also, server unit will be stored in the communication object information of communication information storage part and the communication object information of reception is compared, and both are the communication object information of registration reception simultaneously not.
As mentioned above, adopt present embodiment,, can carry out two-way communication, and can prevent that the traffic of network from becoming huge communicating by letter of carrying out with the communicator that moves.Moreover, server unit is by the 2nd communicator received communication object information from moving, and server unit can remain the communication object information of mobile object.Therefore, where no matter the 2nd communicator move to, and the 1st communicator can both communicate with the 2nd communicator aptly.
Fig. 8 is system's pie graph of present embodiment communication system.
This communication system has the 1st communicator the 801, the 2nd communicator 802 and server unit 403.In this communication system, send calling to the 2nd communicator 802 by the 1st communicator 801.
The 1st communicator 801 has the 1st server unit identifying information storage part 10101, input receiving portion the 10102, the 1st communication object information obtaining section the 10103, the 1st Department of Communication Force 80103, communication object message pick-up portion 80101 and communication control unit 80102.
Communication object message pick-up portion 80101, with during the 2nd communicator 802 is communicated by letter from the 2nd communicator 802 received communication object information.Communication object message pick-up portion 80101 utilizes radio communication device to realize usually.
When communication control unit 80102 receives new communication object information in communication object message pick-up portion 80101, send instructions the represented communication object of communication object information that communication object is switched to receive to the 1st Department of Communication Force 10104.Communication control unit 80102 can utilize software to realize usually, but also available hardware (special circuit) realizes.
The 1st Department of Communication Force 80103 and the 2nd communicator 802 communicate.Also have, in communication process, when communication control unit 80102 receives new communication object information, switch to this new represented communication object of communication object information and communicate.The 1st Department of Communication Force 80103 can utilize radio communication device to realize usually.In addition, in the 1st Department of Communication Force 80103, also comprise and switch to software that the new represented communication object of communication object information communicates etc.
The 2nd communicator 802 comprises: the 2nd Department of Communication Force the 10201, the 2nd communication object information obtaining section the 40201, the 2nd server unit identifying information storage part 40202, change-detection portion 80201 and communication object information sending part 80202.
The situation that the communication object information of 80201 pairs the 2nd communicators of change-detection portion 802 self changes detects.The method that detects this variation can be arbitrarily.Change-detection portion 80201 only when the communication object information change of for example the 2nd communicator 802 self just from radio communication base station received communication object information.In addition, change-detection portion 80201 is for example regularly or frequently from radio communication base station received communication object information, previous communication object information of having stored and the communication object information that receives are made comparisons, inconsistent as both, just be judged as communication object information variation has taken place.
Change-detection portion 80201 utilizes software to realize usually, but also available hardware realizes.
Here, the 2nd Department of Communication Force 10201 has usually from the function of radio communication base station received communication object information.
Communication object information sending part 80202 with the 1st communicator 801 communication processs in, when change-detection portion 80201 detected the communication object change in information, the communication object information that the 2nd communication object information obtaining section 40201 is obtained sent to the 1st communicator 801.
In addition, when communication object information sending part 80202 detected the communication object change in information in change-detection portion 80201, the communication object information that the 2nd communication object information obtaining section 40201 is obtained also sent to server unit 403.Because the 2nd communicator 802 is being communicated by letter with the 1st communicator 801, so communication object information sending part 80202 can be sent to new communication object information the 1st communicator 801.
In addition, the server unit identifying information of server unit 403 can be obtained from the 2nd server unit identifying information storage part 40202.
Communication object information sending part 80202 can utilize radio communication device to realize usually.
Below the action of this communication system is described.
At first, the action to the 1st communicator 801 describes with reference to the flow chart of Fig. 9.
Here, the 1st communicator 801 with the communication object information that obtains the 2nd communicator 802 during the 2nd communicator 802 is communicated by letter from the 2nd communicator 802.By means of this, make the 1st communicator 801 continue to communicate by letter with the 2nd communicator 802.
Again, the action that the 1st communicator 801 and the 2nd communicator 802 begin to communicate by letter, identical with the action with the flowchart text of Fig. 2, therefore explanation is omitted.
(step S901) communication object message pick-up portion 80101 judge whether with the communication process of the 2nd communicator 802 in received communication object information from the 2nd communicator 802.As received communication object information, and just enter step S902, as do not receive communication object information, then return step S901.
(step S902) communication control unit 80102 sends instructions to the 1st Department of Communication Force 10104, makes communication object switch to the represented communication object of communication object information of reception.
In the communicating by letter of (step S903) the 1st Department of Communication Force 80103 and the 2nd communicator 802, the communication object information of the 2nd communicator 802 is switched to new communication object information, continue to communicate by letter with the 2nd communicator 802.
Such processing is carried out usually according to the following steps.
The 1st Department of Communication Force 80103 stops the calling with 802 of the 2nd communicators of former communication object information representation, calls out to the 2nd communicator 802 of new communication object information representation, and the communicating by letter of recovery and the 2nd communicator 802.That is, after the 80103 temporary transient termination communications of the 1st Department of Communication Force, recover communication immediately.Because the speed of this processing is fast, therefore, the 1st communicator 801 sensuously seems to communicate by letter with the user of the 2nd communicator 802 and carries out continuously.
The flow chart that utilizes Figure 10 below describes the action of the 2nd communicator 802.
Here, the 2nd communicator 802 sends to the 1st communicator 801 with during the 1st communicator 801 is communicated by letter with communication object information.Like this, make the 1st communicator 801 continue to communicate by letter with the 2nd communicator 802.
(step S1001) the 2nd communication object information obtaining section 40201 obtains the communication object information of the 2nd communicator 802 self.The method that the 2nd 40201 pairs of communication object information obtaining sections obtain communication object information does not add restriction.For example, the 2nd communication object information obtaining section 40201 is regularly near radio communication base station received communication object information.
(step S1002) change-detection portion 80201 will be not long ago communication object information and step S1001 in the communication object information that receives make comparisons, whether change with the communication object information of judging the 2nd communicator 802.
If communication object information changes, just enter step S1003, if communication object information does not change, then return step S1001.
Here, the 2nd communicator 802 is being stored the communication object information (current communication object information) in the moment recently all the time.That is the 2nd communicator 802 carries out record with new communication object information as current communication object information when communication object information changes.
(step S1003) communication object information sending part 80202 sends to the 1st communicator 801 with the communication object information that obtains among the step S1001.Because the 2nd communicator 802 is being communicated by letter with the 1st communicator 801, so the 2nd communicator 802 can send communication object information.
(step S1004) communication object information sending part 80202 is obtained the server unit identifying information from the 2nd server unit identifying information storage part 40202.
(step S1005) communication object information sending part 80202 sends to the communication object information that obtains among the step S1001 server unit of discerning with the server unit identifying information of obtaining among the step S1004 403.
After this, return step S1001.
Again, in the flow chart of Figure 10, when the 2nd communicator 802 was accepted end signal, then generation was interrupted and is finished.
Also have, in the flow chart of Figure 10, the communication object change in information detects in change-detection portion 80201.
And communication object information also can be done following processing.
Only when the communication object information of the 2nd communicator 802 changed, the 2nd communicator 802 was obtained communication object information from the outside.Under these circumstances, the 2nd communicator 802 also can not made any judgement ground communication object information is sent to the 1st communicator 801 and server unit 403.
Again, in the flow chart of Figure 10, with during the 2nd communicator 802 is communicated by letter, the 2nd communicator 802 sends to server unit 403 with new communication object information at the 1st communicator 801.Again, behind the end of conversation, the 2nd communicator 802 also can send to server unit 403 with new communication object information.
More than the 1st communicator 801 and the 2nd communicator 802 are described.
Described in embodiment 1 and 2, the 1st communicator 801 also can adopt identical structure with the 2nd communicator 802.
Therefore, the 1st communicator 801 also can have communication object information sending part that is equivalent to communication object information sending part 80202 and the change-detection portion that is equivalent to change-detection portion 80201.
In addition, the 2nd communicator 802 also can have the input receiving portion that is equivalent to import receiving portion 10102, be equivalent to the communication object message pick-up portion of communication object message pick-up portion 80101 and the communication control unit that is equivalent to communication control unit 80102.
Below the concrete action of present embodiment communication system is described.
